DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

An embodiment of the present invention will be described hereinafterwith reference to the accompanying drawings.

In the following embodiment, the present invention is applied to a PHS(Personal Handy Phone System) planned to be put into practice in Japan.However, the present invention is not limited to this.

A. System Configuration

FIG. 1 is a view for explaining the system configuration of a PHS.Referring to FIG. 1, a network 1000 is an existing communicationnetwork, which is constituted by, e.g., a PSTN (Public SwitchedTelephone Network), an ISDN (Integrated Services Digital Network), aportable telephone network, and the like. A center 2000 performs overallsystem management, e.g., exchange control of these communicationnetworks, exchange control between communication networks, and exchangecontrol of a PHS.

Base stations 3000a to 3000c are connected to the network 1000. The basestation 3000a is a base station installed outdoors. The base station3000a can be connected by radio to a PHS terminal 4000 in acommunication area a. The base station 3000b is a base station installedin an office and connected to the network 1000 via a PBX (Private BranchExchange). The base station 3000b can be connected by radio to the PHSterminal 4000 in a communication area b. The base station 3000c is abase station installed in a home. The base station 3000c can beconnected to the PHS terminal 4000 in a communication area c. The PHSterminal 4000 can be used in all the communication areas a, b, and c.

Assume that two PHS terminals 4000 are located close, and thecommunication areas of the terminals overlap as indicated by acommunication area d. In this case, the two terminals can perform directcommunication (to be referred to as inter-terminal direct communicationhereinafter) without the mediacy of any base station. Note, however,that this interterminal direct communication can be performed only whenthe two terminals belong to the same base station (in the home or theoffice).

Note that different identification codes are used for the PHS terminal4000 in the home, the office, and the public. In addition, anidentification code used in inter-terminal direct communication is basedon a base station to which the PHS terminal 4000 belongs.

B. PHS Terminal Configuration

The above PHS terminals 4000 can be classified into three types ofterminals depending on the forms of storage of identification codes.

Type A: A plurality of identification codes are stored in the internalmemory of the PHS terminal body.

Type B: Some of a plurality of identification codes are stored in theinternal memory of the PHS terminal body, and the remainingidentification codes are stored in a detachable memory.

Type C: A plurality of detachable memories in which identification codesare stored can be mounted in the PHS terminal body.

Type A

FIG. 2 is a perspective view showing a PHS terminal of type A. FIG. 3 isa block diagram showing the PHS terminal in FIG. 2.

Referring to FIG. 3, reference numeral 1 denotes a control section towhich a high frequency section 2, a modem 4, a TDMA (Time DivisionMultiple Access) processing section 5, a speech CODEC 6, a PCM CODEC 7,a display section 9, a ROM 10, a working memory 11, arecording/reproducing circuit 12, and a message recording memory 13 areconnected to via a bus 18.

The control section 1 controls the overall operation of the terminal inaccordance with control programs stored in the ROM 10. Morespecifically, the control section 1 executes setting/collationprocessing of an identification code and setting/control processing ofan automatic answering telephone function as a well as a generalcommunication process such as a calling/call-incoming process.

In a setting process of an identification code, the control section 1sets one of a plurality of identification codes which is to be used in acalling operation. With this identification code setting process, one ofthe plurality of identification codes stored in a predetermined area ofthe ROM 10 is read out and set in the TDMA processing section 5 (to bedescribed later). In identification code collation process, the controlsection 1 collates a received identification code with the plurality ofidentification codes stored in the ROM 10 in a call-incoming operationto identify the received identification code.

In a setting process of the automatic answering telephone function, thecontrol section 1 sets whether to use the automatic answering telephonefunction in a call-incoming operation. The control section 1 performsthis process for each identification code. In a control process of theautomatic answering telephone function, the control section 1 executesthe automatic answering telephone function if the automatic answeringtelephone function is set on the basis of the identification codecollated by the identification code collation process.

A key input section 8 is connected to the control section 1. As shown inFIG. 2, the key input section 8 has an identification code setting key8d for manually setting an identification code in a calling operationand a ten-key pad 8m for inputting a destination subscriber number andthe like. In addition, the key input section 8 has a calling key 8a fordesignating a call of a destination subscriber number or the like, anend key 8b for disconnecting a channel, a transceiver key 8c fordesignating inter-terminal direct communicating or extensioncommunication, a telephone directory key 8e for designating a mode forsearching a telephone directory database, an automatic answeringtelephone function key 8f for setting the automatic answering telephonefunction, a redial key 8g for redialing a previously dialed number withone touch, a registration key 8h for designating registration of data ineach mode, a delete key 8i for designating deletion of data in eachmode, a selection key 8j to be selected when a service provided by acommunication service company is to be designated, and a power supplykey 8n for turning on/off the power supply of the terminal.

The high frequency section 2 performs a frequency conversion process,and has an antenna switch 2a, a receiving section 2b, a PLL frequencysynthesizer 2c, and a transmitting section 2d. The antenna switch 2a isconnected to an antenna 3. The antenna switch 2a selects the receivingsection 2b or the transmitting section 2d to distribute a signal to thereceiving section 2b or the transmitting section 2d at atransmission/reception timing.

The receiving section 2b frequency-converts a signal input from theantenna 3 via the antenna switch 2a into a reception IF signal by usingtwo mixers (not shown). The transmitting section 2d frequency-converts amodulated wave of a σ/4 shift QPSK (Quadrature Phase Shift Keying)scheme, input from the modem 4, by using a mixer (not shown), andradiates the resultant signal from the antenna 3 via the antenna switch2a. The PLL frequency synthesizer 2c outputs a local oscillation signalfor frequency conversion in the receiving section 2b and thetransmitting section 2d.

The receiving section 2b or the transmitting section 2d of the highfrequency section 2 is connected to the modem 4. The modem 4 performsmodulation/ demodulation processing of the π/4 shift QPSK scheme. In thereception mode, the modem 4 demodulates a reception IF signal from thereceiving section 2b of the high frequency section 2. With thisoperation, the reception IF signal is separated into in-phase componentdata and a quadrature component data to be transferred, as a datastring, to the TDMA processing section 5. In the transmission mode, themodem 4 forms in-phase component data and quadrature component data froma data string transferred from the TDMA processing section 5, performsmodulation of the π/4 shift QPSK scheme, and outputs the resultant datato the transmitting section 2d of the high frequency section 2.

The TDMA processing section 5 is connected to the modem 4. The TDMAprocessing section 5 performs frame synchronization and slot formatprocess. In the reception mode, the TDMA processing section 5 extractsone-slot data from a data string (frame) sent from the modem 4 at apredetermined timing. The TDMA processing section 5 extracts a uniqueword (sync signal) from this data to establish frame synchronization. Inaddition, the TDMA processing section 5 descrambles control and speechdata portions. Thereafter, the TDMA processing section 5 respectivelytransfers the control data and the speech data to the control section 1and the speech CODEC 6. In the transmission mode, the TDMA processingsection 5 adds control data and the like transferred from the controlsection 1 to speech data transferred from the speech CODEC 6 andscrambles the resultant data. Subsequently, the TDMA processing section5 adds a unique word and the like to the data to form one-slottransmission data, inserts the data in a predetermined slot in a frameat a predetermined timing, and outputs the resultant data to the modem4.

The speech CODEC 6 is connected to the TDMA processing section 5. Thespeech CODEC 6 codes/decodes digital data. In the reception mode, thespeech CODEC 6 decodes an ADPCM speech signal sent from the TDMAprocessing section 5 into a PCM speech signal, and outputs it to the PCMCODEC 7. In the transmission mode, the speech CODEC 6 codes a PCM speechsignal sent from the PCM CODEC 7 into an ADPCM speech signal, andoutputs it to the TDMA processing section 5.

The PCM CODEC 7 and the message recording memory 13 (to be describedlater) are connected to the speech CODEC 6. The PCM CODEC 7 performsanalog/digital conversion process for a speech signal. In the receptionmode, the PCM CODEC 7 D/A-converts a PCM speech signal sent from thespeech CODEC 6, and outputs the resultant analog signal to an amplifier14 to drive a loudspeaker 15. In the transmission mode, the PCM CODEC 7A/D-converts an analog speech signal input from a microphone 16, andoutputs the resultant PCM speech signal to the speech CODEC 6. Inaddition, the PCM CODEC 7 controls the volume of the loudspeaker 15 bycontrolling the amplifier in driving the loudspeaker 15, outputs asignal to a ringer 17, and generates/decodes a DTMF (Dual ToneMultifrequency) signal.

The display section 9 displays input data for various control operationsand the resultant data. The ROM 10 is used to store control programs foroperation control performed by the control section 1, a plurality of(two in this embodiment) self-ID data (telephone numbers, PS-ID data,and the like) as identification codes, and the like. The working memory11 is used to temporarily store data used for control performed by thecontrol section 1, and store various conditions set by the key inputsection 8. The message recording memory 13 is used when the automaticanswering telephone function is activated. The message recording memory13 is used to record messages recorded by the user and incomingmessages. The recording/reproducing circuit 12 controlsrecording/reproduction of messages in/from the message recording memory13 under the control of the control section 1.

Type B

The terminal of type B will be described next with reference to theperspective view of FIG. 4 and the block diagram of FIG. 5. The samereference numerals in FIGS. 4 and 5 showing type B denote the same partsas in FIGS. 2 and 3 showing type A, and a description thereof will beomitted.

Type B is characterized in that the terminal has a detachable memory.Some of a plurality of identification codes are stored in a memory (ROM10) of the terminal, and the remaining identification codes are storedin a detachable memory (ID memory). In this embodiment, oneidentification code is stored in the terminal memory, and anotheridentification code is stored in an ID memory 20.

The detachable memory 20 (to be referred to as an ID memory hereinafter)serves to store at least one identification code. An interface 19detects the mounted state of the ID memory 20 through anattachment/detachment detection section 19a, and outputs anattachment/detachment detection signal to a control section 1a. Theinterface 19 connects the ID memory 20 to the bus 18 when the memory ismounted.

The control section 1a is basically the same as the control section 1 inFIG. 3, and controls the overall operation of the terminal in accordancewith control programs stored in the ROM 10. Especially,setting/collation process for an identification code and setting/controlprocess for the automatic answering telephone function are differentfrom those performed by the control section 1.

In a setting process for an identification code, the control section 1asets one of a plurality of identification codes which is to be used in acalling operation. With this identification code setting process, one ofthe plurality of identification codes stored in predetermined areas ofthe ROM 10 and the ID memory 20 is read out and set in the TDMAprocessing section 5. In a collation process for an identification code,the control section 1a collates a received identification code with theplurality of identification codes stored in the ROM 10 and the ID memory20 in a call-incoming operation to identify the received identificationcode.

In addition, the control section 1a recognizes attachment/detachment ofthe ID memory 20 on the basis of an attachment/detachment detectionsignal from the attachment/detachment detection section 19a, and selectsthe identification code in the ROM 10 or the identification code in theID memory 20.

Type C

The terminal of type C will be described next with reference to theperspective view of FIG. 6 and the block diagram of FIG. 7. The samereference numerals in FIGS. 6 and 7 showing type C denote the same partsas in FIGS. 2 and 3 showing type A, and a description thereof will beomitted.

Type C is characterized in that the terminal has a plurality ofdetachable memories. A plurality of identification codes are separatelystored in a plurality of detachable memories (ID memories 22 and 23). Inthis embodiment, one identification code is stored in the ID memory 22,and another identification code is stored in the ID memory 23.

Each of the ID memories 22 and 23 serves to store at least oneidentification code. An interface 21 detects the mounted states of theID memories 22 and 23 through an attachment/detachment detection section21a, and outputs attachment/detachment detection signals to a controlsection 1b. The interface 21 connects the ID memories 22 and 23 to thebus 18 when the memories are mounted.

The control section 1b is basically the same as the control section 1 inFIG. 3, and controls the overall operation of the terminal in accordancewith control programs stored in the ROM 10. Especially, asetting/collation process for an identification code and asetting/control process for the automatic answering telephone functionare different from those performed by the control section 1.

In a setting process for an identification code, the control section 1bsets one of a plurality of identification codes which is to be used in acalling operation. With this identification code setting process, one ofthe plurality of identification codes stored in predetermined areas ofthe ID memories 22 and 23 is read out and set in the TDMA processingsection 5. In a collation process for an identification code, thecontrol section 1b collates a received identification code with theplurality of identification codes stored in the ID memories 22 and 23 ina call-incoming operation to identify the received identification code.

In addition, the control section 1b recognizes attachment/detachment ofthe ID memories 22 and 23 on the basis of attachment/detachmentdetection signals from the attachment/detachment detection section 21a,and selects the identification code in the ID memory 22 or theidentification code in the ID memory 23.

C. Operation in Terminal Communication

When the power supply is turned on, the terminal having one of the abovearrangements (type A, type B, and type C) searches for a control carrier(a radio wave having a predetermined frequency) from a base state to seta control channel which can be currently pulled in.

More specifically, this control carrier is received through the antenna3 and frequency-converted into an IF signal by the receiving section 2bof the high frequency section 2. This reception IF signal is subjectedto π/4 shift QPSK demodulation process in the modem 4 to be convertedinto a data string. This data string undergoes a synchronization processin the TDMA processing section 5, and the resultant control data istransferred to the control section 1. The control section 1 executes acalling process or call-incoming process on the basis of this controldata.

When communication is to be performed, assignment of a communicationchannel is requested with respect to a base station by using the abovecontrol channel. With this operation, a communication path for the basestation is connected by using an assigned communication channel inaccordance with a predetermined procedure. A destination subscribernumber is input via the base station, and communication is started whenthe destination terminal responds.

In the reception mode, a wave received through the antenna 3 isfrequency-converted into an IF signal by the receiving section 2b. Thisreception IF signal is demodulated by the modem 4 to be converted into adata string. After the data is descrambled by the TDMA processingsection 5, the control data is transferred to the control section 1, andthe speech data (ADPCM signal) is transferred to the speech CODEC 6.This speech data is decoded by the speech CODEC 6 to be converted into aPCM signal. This PCM signal is digital/analog-converted by the PCM CODEC7, and the resultant data is supplied to the loudspeaker 15 via theamplifier 14 to generate a sound.

In the transmission mode, a speech signal from the microphone 16 isA/D-converted by the PCM CODEC 7 and coded into an ADPCM code by thespeech CODEC 6. This coded speech data is subjected to scrambling or thelike in the TDMA processing section 5. The resultant data is inserted ina slot at a predetermined timing. The modem 4 performs π/4 shift QPSKmodulation processing for the data. The transmitting section 2dfrequency-converts the data into a signal in a 1.9-GHz band. The signalis then radiated from the antenna 3.

D. Types and Combinations of Identification Codes

Identification codes used in the PHS:

1 Private subscriber numbers assigned to private base stations.

In practice, these codes are based on an assumption that acall-incoming/calling process is performed by terminals. For thisreason, such a private subscriber number can be designated when aterminal is connected to a private base station by using a private basestation ID number (CS-ID) and a terminal ID number (PS-ID).

2 (M Public subscriber numbers assigned for communication via publicbase stations.

3 Terminal numbers assigned for extension communication orinter-terminal direct communication.

In practice, when inter-terminal direct communication is to beperformed, a terminal number is used together with part (system callcode) of a CS-ID to indicate a subordinate relationship with a basestation. That is, this system call code is used, with a terminal numberbeing added thereto, to call a destination terminal.

Private and public subscriber numbers are so-called telephone numbersassigned by a communication service company. A private subscriber numberis assigned to a communication line connected to the private basestation 3000c or 3000b in FIG. 1. In practice, this private subscribernumber is assigned to the private base station 3000c or 3000b. A publicsubscriber number is assigned to the terminal 4000 which can be calledvia the public base station 3000a.

A terminal number is provided by the user and is used to performextension communication or inter-terminal direct communication betweenthe terminals 4000 via the private base station 3000c or 3000b.

Various combinations of these identification codes are available.Several combinations will be presented as typical examples. Note thatsome combinations are characteristic depending on the above types ofterminals.

Type A

(1) private subscriber number+public subscriber number+terminal number(including a system call code),

(2) a plurality of private subscriber numbers,

(3) a plurality of public subscriber numbers,

(4) a plurality of terminal numbers (including system call codes).

Type B

(1) terminal body: private subscriber number

ID memory: public subscriber number+terminal number (including a systemcall code),

(2) terminal body: public subscriber number

ID memory: private subscriber number+terminal number (including a systemcall code).

Type C

(1) private subscriber number+public subscriber number+terminal number(including a system call code),

(2) a plurality of private subscriber numbers,

(3) a plurality of public subscriber numbers,

(4) a plurality of terminal numbers (including system call codes).

According to type A, a plurality of identification codes in the ROM 10of the terminal body are selected. According to type C, a plurality ofdetachable ID memories (22 and 23) in which identification codes arerespectively stored are selected. That is, types A and C are the same inthat identification codes are selected from the same type of medium.

However, type B is different from the above types in that identificationcodes are selected from the terminal ROM 10 and the ID memory 20. Thatis, a combination (1) is optimal when priority is given to the indooruse of the terminal. However, a combination (2) is optimal when priorityis given to the outdoor use of the terminal. As described above, theoptimal storage method changes depending on the life-style of the user.If one ID memory is fixed to the terminal body of type C, while theother memory is detachably mounted, the terminal is equivalent to theterminal of type B.

The above combinations are merely examples and hence may be furthercombined with each other.

The memory structure of part of the ROM 10 of the terminal body or theID memory 20, 22, or 23 will be described next with reference to FIG. 8.

Referring to FIG. 8, "PS-ID" and "CS-ID" are ID data of a terminal and abase station. These ID data are used to connect the terminal, the basestation, and a radio channel to each other. Subscriber number is aso-called telephone number, which is used to execute radio communicationvia a public base station. Terminal number is a number assigned to aterminal by the user. This terminal number is used when a destinationterminal is called or the our terminal is called by a destinationterminal in performing extension communication or inter-terminal directcommunication via a private base station. Note that the our terminalnumber and the destination terminal number are stored in the terminalnumber. System call code is a code used, with a terminal number beingadded thereto, to execute inter-terminal direct communication. Thissystem call code is part of the CS-ID data of a private base station.User area is an area for storing the individual information of the user.

E. Calling Operation

Methods of selecting identification codes in calling operations will bedescribed next. Various cases are assumed in the selection methods.

Case 1: The user performs a switching operation by operating the keyinput section of the terminal body.

Case 2: Public and private subscriber numbers are selectively switchedin accordance with a pull-in radio wave from a base station. Thisoperation is a characteristic for only a terminal having public andprivate subscriber numbers.

Case 3: A switching operation is structurally performed. This operationis a characteristic for only a terminal having a detachable ID memory.That is, this method can be applied to type B or C.

In the case 1, one identification code is selected from a plurality ofidentification codes by operating the key input section 8, and a callingoperation is performed. FIG. 9 shows the case 1. In the case shown inFIG. 9, one subscriber number is selected from two identification codes(private and public subscriber numbers). With this operation, one of thesubscriber numbers which is to be used to perform a calling operation isdetermined. When this subscriber number is transmitted, an object to becharged is determined. In this case, the private subscriber number is anumber assigned to a private base station in practice. A terminal candesignate the private subscriber number by designating the CS-ID data ofthe private base station.

More particularly, referring to FIG. 9, first a subscriber number(private or public subscriber number) as an object to be charged isdesignated by operating the identification code setting key 8d of thekey input section 8 (steps 101 and 102). If it is determined in step 101that the private subscriber number is selected, the CS-ID and PS-ID dataof the private base station are read out from a memory (the terminal ROM10 or the ID memory 20, 22, or 23) (step 103), and are set, as linkinformation for the private base station, in the TDMA processing section5 (step 104). If it is determined in step 102 that the public subscribernumber is selected, the CS-ID stored in the working memory 11 and thePS-ID data stored in a memory (the ROM 10 or the ID memory 20, 22, or23) are read out and set, as link information for the public basestation, in the TDMA processing section 5 (steps 105 and 106). Thepublic subscriber number stored, as caller information, in a memory (theterminal ROM 10 or the ID memory 20, 22, or 23) is read out and set inthe TDMA processing section 5 (steps 107 and 108).

With this operation, one of the private base stations 3000c and 3000b orthe public base station 3000a to which a communication channel is to beconnected is determined. When the subscriber number of a person to becalled is input (step 109), and the calling key 8a of the key inputsection 8 is operated, a link with the corresponding base station isestablished on the basis of the CD-ID data set in step 104 or 106. Thedestination subscriber number is transmitted to the private base stationor the caller ID information and the destination subscriber number aretransmitted to the public base station in accordance with apredetermined procedure (step 108).

In the case 2, a radio wave from a base station is pulled in to specifythe base station which can be currently connected. With this operation,a subscriber number as an object to be charged is automatically selectedto perform a calling operation. FIG. 10 shows the case 2. In the caseshown in FIG. 10, a subscriber number assigned to a home base station(in practice, this subscriber number is selected by designating theCS-ID data of the home base station), a subscriber number assigned to anoffice base station (in practice, this subscriber number is selected bydesignating the CS-ID data of the office base station), or a subscribernumber assigned to a public base station is selected.

In other words, referring to FIG. 10, a control channel from a basestation which can be currently connected is pulled in to extract controlinformation (CS-ID data and the like) from the base station (step 201).The base station which can be currently connected is identified (home,office, or public base station) on the basis of this CS-ID data (steps202 and 203). If it is determined in step 203 that the base station isthe home base station, the CS-ID data of the home base station is readout from the ROM 10 or the ID memory 20, 22, or 23 (step 204) and isset, as calling information, in the TDMA processing section 5 (step205). If it is determined in step 203 that the base station is theoffice base station, the CS-ID data of the office base station is readout from the ROM 10 or the ID memory 20, 22, or 23 (step 206) and isset, as calling information, in the TDMA processing section 5 (step207). If it is determined in step 202 that the base station is thepublic base station, the CS-ID data of the public base station is readout from the RAM 11 and is set, as calling information, in the TDMAprocessing section 5 (steps 208 and 209). In addition, the publicsubscriber number is read out from the ROM 10 or the ID memory 20, 22,or 23 and is set, as caller information, in the TDMA processing section5 (steps 210 and 211).

While the calling information is set, the destination subscriber numberof a person to be called is input (step 212), and the calling key 8a ofthe key input section 8 is operated. As a result, a link with thecorresponding base station is established. If a link with a private basestation is established, the destination subscriber number is transmittedto the base station. If a link with the public base station isestablished, the destination subscriber number and the callerinformation are transmitted to the base station (step 213). In thiscase, the home or office base station outputs the private subscribernumber assigned as the caller information.

In the case 3, identification information is switched in accordance withthe mounted state of a detachable memory. FIG. 11 shows the case 3. Inthe case shown in FIG. 11, private CS-ID data is stored in the ROM 10 ofthe terminal body, and a system call code (part of the private CS-IDdata) for inter-terminal direct communication is stored in the ID memory20. The ID memory 20 is mounted in the terminal body.

The control section 1a determines the mounted state of the ID memory 20on the basis of an attachment/detachment detection signal from theattachment/detachment detection section 19a (step 401). If it isdetermined in step 401 that the ID memory 20 is mounted, the system callcode stored in the ID memory 20 is read out and set in the TDMAprocessing section 5 (steps 402 and 403). If it is determined in step401 that the ID memory 20 is not mounted, the private CS-ID data isloaded from the ROM 10 of the terminal body to be set in the TDMAprocessing section 5 (steps 404 and 405). If the system call code fromthe ID memory 20 is set, a three digit of destination terminal number isinput. If the private CS-ID data from the ROM 10 is set, a destinationsubscriber number is input (step 406). The calling key 8a of the keyinput section 8 is then operated. In this case, if the ID memory 20 ismounted, the system call code is output, with the destination terminalnumber being added thereto, by using-a carrier for inter-terminal directcommunication. If the private CS-ID data from the ROM 10 is set, a linkwith the private base station is established, and the destinationsubscriber number is output.

In the cases 1 to 3 described above, the stored contents of the ROM 10or the ID memory 20, 22, or 23 are merely examples. Various combinationsother than the above combinations are available, as described above. Thecases 1 to 3 can be properly changed in accordance with suchcombinations. According to the above description, for example, oneidentification code corresponds to one memory. If, however, a pluralityof identification codes correspond to one memory, one of the pluralityof identification codes must be selected. In addition, if different codeforms are used depending on selected identification codes, theidentification codes must be stored in corresponding forms.

F. Call-incoming Operation

Various call-incoming operations are conceivable. For example, since aplurality of incoming calls can be received by one terminal, prioritymust be given to a specific one of the incoming calls. Also, a specificoperation for a call to a subscriber number for which no call-incomingoperation is desired must be determined (in consideration of theautomatic answering telephone function). These are the main concerns ina call-incoming process.

Type α: Call-incoming process is set in advance by a key operation.Normal call-incoming process and the automatic answering telephonefunction are set.

Type β: Call-incoming process is set in accordance with a schedule(time).

i) Explanation of Type α

FIGS. 12A and 12B are flow charts for explaining type α. In thisembodiment, a standby state ("standby", "automatic answering telephone",or "call-incoming rejection") is set in the working memory 11 in advancefor each subscriber number. For the sake of descriptive convenience, acall-incoming process based on two subscriber numbers (a privatesubscriber number and a public subscriber number) will be describedbelow. Note that a call-incoming process based on the public subscribernumber is performed by the terminal itself. However, in a call-incomingprocess based on the private subscriber number, the terminal is calledafter an incoming call is received by a private base station.

As shown in FIG. 12A, each of the control sections 1, 1a, and 1b checksfor each subscriber number in a standby state whether a call-incomingprocess is performed (step 501). If it is determined that acall-incoming process is performed with respect to one subscribernumber, it is checked whether speech communication is being performed onthe basis of another subscriber number (private or public subscribernumber) (step 502). If the busy state is not set, it is checked whetherthe call-incoming process is performed with respect to the privatesubscriber number (step 503). That is, a specific call-incoming processis determined by comparing the subscriber number in the control dataextracted by the TDMA processing section 5 with the subscriber numberstored in the ROM 10 in the terminal or the detachable ID memory 20, 22,or 23.

If it is determined that the call-incoming process is performed withrespect to the private subscriber number, it is checked whether thestandby state stored in the working memory 11 for the private subscribernumber is "standby" (step 504). If it is determined that the standbystate is "standby", information indicating that the call-incomingprocess is performed with respect to the private subscriber number isdisplayed on the display section 9 (step 505). In addition, a ringingtone for the private subscriber number is generated (step 506). When theuser operates the communication key of the key input section 8,communication is started (step 507).

If it is determined in step 504 that the standby state is not "standby",it is checked on the basis of the stored contents of the working memory11 whether the standby state is "automatic answering telephone" (step508). If "automatic answering telephone" is set, the channel isconnected, and an outgoing message stored in the message recordingmemory 13 in advance is read out by the recording/reproducing circuit12. The transmission signal is then output from the antenna 3 to thebase station via the speech CODEC 6, the TDHA processing section 5, themodem 4, and the high frequency section 2 (step 509). When thedestination terminal receives the message input via the base station,the message is recorded in the message recording memory 13 in a reverseorder to the above procedures.

If it is determined in step 508 that the standby state is not "automaticanswering telephone", it is determined that the standby state is"call-incoming rejection", and a call-incoming rejection signal istransmitted to the base station (step 510).

If it is determined in step 503 that the call-income process is notperformed with respect to the private subscriber number, it isdetermined that the call-income process is performed with respect to thepublic subscriber number. Therefore, in step 515 in FIG. 12B, it ischecked whether the standby state stored in the working memory 11 withrespect to the public subscriber number is "standby" (step 515). If"standby" is determined, information indicating that the call-incomeprocess is performed with respect to the public subscriber number isdisplayed on the display section 9 in step 516. In step 517, a ringingtone for the public subscriber number is generated. When the useroperates the communication key of the key input section 8 in step 518,communication is started.

If it is determined in step 515 that the standby state is not "standby",it is checked in step 519 whether the standby state stored in theworking memory 11 is "automatic answering telephone" (step 519). If"automatic answering telephone" is determined, the channel is connectedin step 520, and the outgoing message stored in the message recordingmemory 13 is read out by the recording/reproducing circuit 12. Thetransmission signal is then output from the antenna 3 to the basestation via the speech CODEC 6, the TDMA processing section 5, the modem4, and the high frequency section 2. When the destination terminalreceives the message input via the base station, the message is recordedin the message recording memory 13 in a reverse order to the aboveprocedures.

If it is determined in step 519 that the standby state is not "automaticanswering telephone", it is determined that the standby state is"call-incoming rejection", and a call-incoming rejection signal istransmitted to the base station (step 521).

Referring back to FIG. 12A, if it is determined in step 502 that thebusy state is set, it is checked whether the current call-incomingprocess is performed with respect to the private subscriber number (step511). If it is determined that the call-incoming process is performedwith respect to the private subscriber number, it is checked on thebasis of the stored contents of the working memory 11 whether thestandby state corresponding to the subscriber number is "standby" (step512). If "standby" is determined in step 512, information indicatingthat the call-incoming process is performed with respect to the privatesubscriber number is displayed on the display section 9 (step 513). Inaddition, a response signal indicating a busy state is output to thecaller (step 514).

If it is determined in step 512 that the standby state is not "standby",an automatic answering telephone outgoing message (steps 508 and 509) ora call-incoming rejection signal (steps 508 and 510) is transmitted onthe basis of the standby state "automatic answering telephone" or"call-incoming rejection", as described above.

If it is determined in step 511 that the call-income process is notperformed with respect to the private subscriber number, it isdetermined that the call-income process is performed with respect to thepublic subscriber number. Therefore, the flow advances to step 522 tocheck on the basis of the stored contents of the working memory 11whether the standby state corresponding to the public subscriber numberis "standby" (step 522). If "standby" is determined in step 522,information indicating that the call-incoming process is performed withrespect to the public subscriber number is displayed on the displaysection 9 (step 523). In addition, a response signal indicating a busystate is output to the caller (step 524).

If it is determined in step 522 that the standby state is not "standby",an automatic answering telephone outgoing message (steps 519 and 520) ora call-incoming rejection signal (steps 519 and 521) is transmitted onthe basis of the standby state "automatic answering telephone" or"call-incoming rejection", as described above.

ii) Explanation of Type β

FIGS. 13 and 14 are views for explaining type β. FIG. 13 shows therelationship between a schedule and the standby state corresponding toeach subscriber number (this view corresponds to a portion of theworking memory 11). FIG. 14 is a flow chart showing an operation basedon the contents of the working memory 11. For the sake of descriptiveconvenience, as in the description of type A, a case of two subscribernumbers will be described below. In order to describe an actual methodof using subscriber numbers, it is assumed that one subscriber number isfor private use (represented by "P"), and the other subscriber number isfor business use (represented by "W"). In this method, an automatictelephone answering mode (represented by "sleep") and a normalcall-incoming mode (represented by "wake up") are switched in accordancewith a schedule.

Assume that in FIG. 13, the schedule in the working memory 11 is setlike the schedule. During sleeping hours, call-incoming process for thesubscriber numbers for private use and business use are set in "sleep".During working hours, the subscriber number for private use is set in"sleep", and the subscriber number for private use is set in "wake up".Even during working hours, in a conference, the subscriber number forbusiness use is changed to "sleep". During private hours, the subscribernumber for private use is set in "wake up", and the subscriber numberfor business use is set in "sleep". Note that an outgoing message during"sleep" is changed in accordance with the contents of a schedule. Forexample, during sleeping hours, "I am in bed now, so please leave amessage" is output. If in a conference, "I am in conference, so pleaseleave a message" is output.

The flow chart shown in FIG. 14 is executed on the basis of the contentsset in the working memory 11. If call-incoming process is performed in astandby state (step 601), it is checked, on the basis of a plurality ofsubscriber numbers stored in the ROM 10 of the terminal body or thedetachable ID memory 20, 22, or 23, whether this call-incoming processis performed with respect to the subscriber number for private use (step602). If the call-incoming process is performed with respect to thesubscriber number for private use, it is checked in step 603, on thebasis of the conditions stored in the working memory 11, whether thesubscriber number of private use is in "wake up" (normal call-incomingmode).

If the normal call-incoming mode is determined, information indicatingthat a call-incoming process is performed with respect to the subscribernumber of private use is displayed on the display section 9 (step 604).In addition, a ringing tone indicating that a call-incoming process isperformed with respect to the subscriber number of private use isgenerated (step 605). When the user operates the communication key ofthe key input section 8 in response to this ringing tone, speechcommunication is started.

If it is determined in step 603 that the standby state is "sleep", theflow advances to step 607. In step 607, an outgoing message which isstored in the message recording memory 13 by the user is read out by therecording/reproducing circuit 12 and is transmitted to the caller. Whenthe caller inputs a message in response to this message, the incomingmessage is stored in the message recording memory 13.

If it is determined in step 602 that the call-incoming process is notperformed with respect to the subscriber number for private use, it isdetermined that the call-incoming process is performed with respect tothe subscriber number for business use. It is then checked whether thestandby state corresponding to the subscriber number for business use inworking memory 11 is "wake up" (step 608). If "wake up" is determined,information indicating that call-incoming process is performed withrespect to the subscriber number for business use is displayed (step609). In addition, in step 610, a ringing tone indicating that acall-incoming process is performed with respect to the subscriber numberfor business use is generated (step 610). When the user operates thecommunication key of the key input section 8 in response to this ringingtone, communication is started.

If it is determined in step 608 that the standby state is "sleep", theflow advances to step 612. In step 612, an outgoing message which isstored in the message recording memory 13 by the user is read out by therecording/reproducing circuit 12 and is transmitted to the caller. Whenthe caller inputs a message in response to this message, the incomingmessage is stored in the message recording memory 13.

In the above call-incoming operation, call-incoming process is switchedin accordance with the two subscriber numbers. However, the presentinvention is not limited to this. For example, a private subscribernumber and a public subscriber number or an ID number for inter-terminaldirect communication may be switched.

In addition, in the present invention, calling/call-incoming process isexecuted via a public base station by using a public subscriber number.However, the present invention is not limited to this. If the center2000 has a database in which public subscriber numbers are stored incorrespondence with PS-ID data, a calling/call-incoming process can beexecuted by using PS-ID data.

Additional advantages and modifications will readily occur to thoseskilled in the art. Therefore, the invention in its broader aspects isnot limited to the specific details, and representative devices shownand described herein. Accordingly, various modifications may be madewithout departing from the spirit or scope of the general inventiveconcept as defined by the appended claims and their equivalents.
